First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-phase trial tests whether metformin, a widely used diabetes drug, can prevent muscle loss and insulin resistance in healthy older adults during five days of bed rest. Researchers will measure changes in muscle size and insulin sensitivity. The study involves 64 participants aged 60 and older at the University of Utah.
What this could mean

Active substance
Metformin (an oral diabetes drug)
What this could lead to
If it works, this could point toward a way to protect muscle health in older adults during periods of inactivity, like bed rest.
What could go wrong
This is a very small, early-phase study (64 people) testing a short-term effect. Results may not apply to real-world aging or long-term use, and metformin can cause stomach upset.
